. ing stoves and ovens; and it resides in the provision ofmeans whereby it is possible to use oil or any other liquid fuel in almost I any stovev or oven without much alteration even though designed primarllyfor solid fuels.

The invention consists of a number of sockets placed above each other, so as to permit the fuel to drip down from one to another and while evaporating an intense combustion is obtained.

One embodiment f the invention is illustrated in the drawing:

Figure 1 shows a vertical section of the lower part of a stove,

Fig. 2 a cross sectlon of the same, Fig. 3 a modified detail.

The plate 6 forms the bottom of the fire space a in a stove and generally bears the ate. On the plate 6 a conical socket or socket 9', but smaller in size, is similarly fitted upon the upper end of the funnel e, and maintained in place thereon by its projections h. Several additional sockets or funnels can in the same manner be put on the top of each other according to circumstances, I

The upper socket is covered by a plate 2', resting on projections j leaving a little space between the funnel and the plate. A pipe is, provided with a valve Z, leads from a tank m provided with a charging hole 1, and is carried into the stove at the bottom thereof, whence it passes up through the funnels into and through the plate z, the latter having a central opening in which the mouth of said pipe fits. Around this opening the plate a is provided with small pipes or nipples p,

which project a little way above the plate,

the bores 0 of said nipples forming air openv ings. The plate 2' has besides projections g on which the plate 1' rests, which latter is sufliciently large as to cover the greater part of the stove.

On openin the valve Z the liquid fuel passes throng the mouth of the pipe in and spreads over plate 2', from which it drips down on the funnel g and thence down thev other funnels. Now when the fuel is ignited the heat produced will heat the funnels which will convert the fuel dripping down their sides into gas and thus intensify the combustion. Any kind of liquid fuel, even coal-tar, can be employed, and because air can pass through the spaces between the several funnels the combustion will be as intense and perfect as possible. The plate T will direct the flames toward the walls of the stove, thus heating the said walls and in this way diffusing the heat in the room.

Instead of the projections h and f being cast on the internal sides of the upper funnel, they can be cast on the external sides of the lower funnel. The form of the funnels and the plates can be made to correspond to the stove, in which they are to be placed. The channel 03 serves to receive the fuel which has not evaporated.

When very light fluid oils are used, a plate 8 will be used instead of plate 2'', as is shown in Fig. 3. This plate 8 has no air holes but is covered by a convex plate t. The fuel will in this case be reduced to gas on the plate 8 and will be mixed with air when passin the edge of the plate 13, and thus a per ect combustion will be obtained. In order to produce as much heat as ossible, the interior of the stove can be ed with broken bricks or the like above and below the burner.

Having now particularly described and ascertained the nature of my said invention and in what manner the same is to be performed, I declare that what I claim is:

1. In an oil burner, the combination of a plurality of superposed conical members; a distributing plate mounted above the uppermost conical member and having a central 2. In an oil burner, the combination of a plurality of superposed conical members; a

distributing plate mounted above the uppermost conical member and having a central opening; and .an oil supply pipe having its outlet end fitted in said opening; said plate being provided around said opening with a series of upwardly-projecting nipples, the bores of which form air holes.

3. In an oil burner, the combination of a plurality of superposed conical members; a distributing plate mounted above the uppermost conical member and having a central opening; an oil supply pipe having its outlet end fitted in said opening; said plate having air holes formed through it around said opening; and a spreader plate mounted above said distributing plate.

4. In an oil burner, the combination of a plurality of interfitted, frusto-conical members arranged in vertical series, the successive members increasing in size from top to bottom of the series, so that the Wall of each member will form a substantial prolongation of the next lower member; a distributing plate mounted directly upon the topmost conical member and having a central opening; and a spreader plate mounted directly above the distributing plate.
